"Social Media for business: Why it matters to everyone", by Stephen Baker.

"The big points are that everyone needs social media, to learn, connect, respond, and be seen. I argue toward the end that a crucial skill in this changing world–and this might surprise some people–is good writing. Our words are our ambassadors."

An excellent essay on social media by +Stephen Baker is attached. Our ability to communicate is a critical 21st century skill. This is certainly true in mathematics as well. I always remind my students, "obtaining an answer is not our only goal, we must communicate to others how we solved the problem!" So often I receive assignments that are totally unreadable — answers magically circled somewhere in the middle of a sea of scratch calculations. Would your future project manager approve of that?
